Abstract
A scavenging device for recapturing charged carrier particles from a moving image-bearing surface includes a first pickup member and a second pickup member. The first pickup member is mounted adjacent toner and carrier particles on the image-bearing member, and is biased electrically to a polarity relatively opposite to the polarity of the charged carrier particles. The second pickup member is also mounted adjacent toner and carrier particles on the image-bearing member to be effective at a point downstream of the first pickup member. The second member, as such, is electrically grounded for capturing from the image-bearing member wrong sign carrier particles.
